Appendix A : CX29600 Software Overview
The Mindspeed CX29600 software consists of two layers. The purpose of the
lowest layer, the Hardware Programming Interface (HPI), is to abstract the
hardware details from the interface user. The HPI provides a broad interface
allowing access to all (software accessible) device features. The Device Driver
Programming Interface (DDPI) utilizes the HPI to provide an interface closer to a
device driver’s requirements. The software is designed to be easily portable across
operating systems and hardware system architectures.
